Place a saucepan over medium heat and melt the butter.
Add minced garlic and sauté for 1–2 minutes until fragrant.
Sprinkle in flour and stir to form a paste (roux).
Slowly pour in milk, whisking constantly to prevent lumps. Simmer until slightly thickened.
Add the thawed, well-drained spinach. Stir until fully combined and heated through.
Season with salt and pepper to taste. Add a pinch of nutmeg if desired.
Serve warm as a side dish or spooned over toast, grains, or proteins.

Start with well-drained spinach to avoid watery sauce. Whisk steadily while adding milk for a smooth finish.
